The glowing purple dust rubs off of Sylvrin.

The Theran form of Sylvrin appears before you.

Odd enough, because it gets rubbed off BEFORE she comes in, but that's cosmetic BS. Look down below when I "look" in the room.

The Bar of the Eternal Star
A large wooden bar fills the entire southern wall. Made of a rare red tree,
it has been finely carved and oiled so that it shines in the dim light. Food
is scarce near here but mugs and cups of every kind crowd the bar and
swing through the air for a toast. Shelves behind the bar hold the rare
ales and beers while large barrels sit stacked with the poorer drinks.
Stools are scattered about for people to sit, but most stand so they can
stomp and dance when the moment takes them. A large tapestry hangs
over the shelves behind the bar. People swarm in and crowd, pressing to
be nearer, calling out drinks and stumbling to hold on to their own. To
the north the crowd swirls, dancing and singing in a common area. Eastwards,
patrons cheer and groan noisily and long tables filled with food lie
west.


Soloegel is here.
(Purple Aura) Sylvrin is here.
Mufasaw is resting here.
Aneriasha is here.
A stout dwarf bouncer hefts his cudgel and looks for trouble.
A huge, fat man looks distracted as he passes out drinks.

(Few hours later)

The glowing purple dust rubs off of Sylvrin.

She wasn't dusted again, I "looked" at the room about 5-10 seconds after she came in, and no one fogged, etc.
